In her first public comments about her split with Justin Bieber, Selena Gomez joked on Monday’s Late Show With David Letterman that she made her ex boyfriend cry — earning her a fist bump from the wry host.

Letterman perfectly set up the lovely Gomez,saying, “Last time you were here, you were with a Justin Bieber. That’s not going on now.”

The Spring Breakers star, 20, affirmed to Letterman that she and the Biebs, 19, were no longer a couple, replying: “No, I’m single. I’m so good.”

Letterman then cracked, “Now, the last time he was on, he and I got into a conversation and he said something and I said something, and then he said something and I said something, and I made him cry.”
